linux安装mysql5.7.19

1、解压文件

[root@localhost software]# tar -xzvf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz -C /usr/local/

2、修改文件

[root@localhost software]# mv mysql-5.7.19-linux-glibc2.12-x86_64 mysql

3、检查库文件是否有删除，若有便删除（linux系统自带的）

[root@localhost mysql]# rpm -qa | grep mysql

删除

[root@localhost mysql]# rm -e –-nodeps mysql-libs-5.1.52.x86_64

4、检查mysql组和用户是否存在，如无创建：

  [root @localhost ~]# cat /etc/group | grep mysql

  [root@localhost ~]# cat /etc/passwd |grep mysql

 

  创建

  [root@localhost ~]#groupadd mysql

  [root@localhost ~]#useradd -r -g mysql mysql

5、在mysql下添加data目录

[root@localhost mysql]# mkdir data

6、更改mysql目录下所有的目录及文件夹所属组合用户

[root@localhost /]# cd /usr/local/ 
[root@localhost local]# chown -R mysql mysql/ 
[root@localhost local]# chgrp -R mysql mysql/ 
[root@localhost local]# cd mysql/ 
[root@localhost mysql]# ls -l 
total 40 
drwxr-xr-x. 2 mysql mysql 4096 Aug 31 16:45 bin 
-rw-r--r--. 1 mysql mysql 17987 Jun 22 22:13 COPYING 
drwxr-xr-x. 2 mysql mysql 6 Aug 31 16:48 data

drwxr-xr-x. 5 mysql mysql 4096 Aug 31 16:45 lib 
drwxr-xr-x. 4 mysql mysql 28 Aug 31 16:45 man 
-rw-r--r--. 1 mysql mysql 2478 Jun 22 22:13 README 
drwxr-xr-x. 28 mysql mysql 4096 Aug 31 16:45 share 
drwxr-xr-x. 2 mysql mysql 86 Aug 31 16:45 support-files

8、安装和初始化数据库：

[root@localhost bin]# ./mysqld --initialize --user=mysql --basedir=/usr/local/mysql/--datadir=/usr/local/mysql/data/
2017-08-31T08:50:23.910440Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 
2017-08-31T08:50:23.910635Z 0 [ERROR] Can't find error-message file '/usr/local/mysql/--datadir=/usr/local/mysql/data/share/errmsg.sys'. Check error-message file location and 'lc-messages-dir' con

2017-08-31T08:50:24.896645Z 1 [Note] A temporary password is generated for root@localhost: gFamcspKm2+u

报错[ERROR] Can’t find error-message file ‘/usr/local/mysql/–datadir=/usr/local/mysql/data/share/errmsg.sys’. Check error-message file location and ‘lc-messages-dir’ con
解决：
[root@dbserver bin]# ./mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --lc_messages_dir=/usr/local/mysql/share --lc_messages=en_US
2017-08-31T09:00:54.941514Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

2017-08-31T09:00:56.672453Z 1 [Note] A temporary password is generated for root@localhost: qfuqvCsHb2!.

9、配置my.cnf 

  接下来进入/usr/local/mysql/support-files/目录下，查看是否存在my-default.cnf文件，如果存在直接copy到/etc/my.cnf文件中

  [root @localhost mysql]# cp -a ./support-files/my-default.cnf /etc/my.cnf

  如果不存在my-default.cnf文件,则在/etc/目录下创建my.cnf,并写入以下内容

  [mysqld]

  skip-name-resolve

  lower_case_table_names=1

  port = 3306

  sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

10、启动服务

[root@localhost mysql]# cd bin/ 
[root@localhost bin]# ./mysqld_safe --user=mysql & 
[2] 10436 
[root@dbserver bin]# Logging to '/var/log/mysql/mysql.log'. 
2017-08-31T09:52:15.806633Z mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 
2017-08-31T09:52:16.292949Z mysqld_safe mysqld from pid file /var/run/mysql/mysql.pid ended

11、将mysqld服务加入开机自启动项。 

[root@localhost support-files]# cp mysql.server /etc/init.d/mysql
[root@localhost support-files]# chmod +x /etc/init.d/mysql
-- 把mysql注册为开机启动的服务
[root@localhost support-files]# chkconfig --add mysql
-- 查看是否添加成功
[root@localhost support-files]# chkconfig --list mysql

12、用命令启动服务：

[root@localhost bin]# service mysql start
Starting MySQL.Logging to '/var/log/mysql/mysql.log'.
ERROR! The server quit without updating PID file (/var/lib/mysql/dbserver.pid).

解决
[root@localhost mysql]# rm /etc/my.cnf
[root@localhost mysql]# /etc/init.d/mysql start
Starting MySQL.Logging to '/usr/local/mysql/data/dbserver.err'.
SUCCESS!
[root@localhost mysql]# service mysql start
Starting MySQL SUCCESS! 

13、登录mysql

[root@localhost bin]# ./mysql -u root -p

14、设置密码

mysql> set password=password("root");
Query OK, 0 rows affected, 1 warning (0.00 sec)

15、设置远程登录权限

mysql> grant all privileges on *.* to'root' @'%' identified by 'root'; 
Query OK, 0 rows affected, 1 warning (0.00 sec) 
mysql> flush privileges; 
Query OK, 0 rows affected (0.06 sec) 
mysql> quit 
Bye 

到此为止，整个安装过程结束。
